R ILv JOINT.

Application filed. November 17, 1927. Serial No 233,944.

My invention relates to improvements in rail joints, wherein the same aims to provide a novel rail joint construction which will eliminate the necessity of forming openings a in the end portions of the abutting rails as is the necessity in the adaptation of presentday types of joints. f p

In breaking the joint in the trackage of railways, it is necessary atpresent to remove m all of the bolts extending through the respective abutting rail ends for securing the clamping plate against the opposed sides of the rail ends, before the rails can be disengaged from the joint securing structure. The main object of my invention is to provide a structure for clamping the respective abutting end portions of rail sections together, without the necessity of employing bolts or other elements adapted to project through openings in the rail ends.

Another object resides in providing a pair of clamping plates adapted to engage opposed sides of the rail joint, and having means associated therewith, whereby said clamp plates may be adjusted to tightly engage opposed sides of the joint.

Another object resides in providing such a rail joint securing construction, wherein the rails may be detached therefrom without the necessity of entirely removing the clamping portion of the structure.

Other very novel objects and advantages of my improved rail joint construction, will become apparent as the same is better understood from the specification andclaims to follow.

In the drawing Figure 1 represents a top plan view of the rail joint securing structure in association with the abutting end portions of a pair of conventional rail sections, and

Fig. 2 is a transverse sectional view taken substantially on the line 22 of Fig; 1.

Now for a, more detail description of my inventioml refer to the drawings, in which like numerals will designate like parts. For the purpose of illustrating the manner in which my improved rail oint securing struc ture is adapted inassociation with the abutting ends of rail sections, I indicate A and B fragmentarily,,to represent the abutting ends of a pair of conventional rails. These rails are formed in the usual manner with a fin base plate, web portion and the treadportion supported upon the web.

elongated extent, the longitudinal edges thcreor being formed with spike receiving notches 2. The abutting ends of the rails are to be supported upon the base plate sub-- 'stantially toward and parallel to one 1on gitudinal edge thereof.

Slightly inwardly fr in this longitudinal edge, an upstanding inwardly bent flange 3 is provided, while the other longitudinal portion of the plate is inclined slightly upwardly as at. 4. This inclined portion of the plate is provided with a depending end wall 5, and a longitudinally depending edge wal 6, said walls'having their lower edges-in flush relation with the bottom surface of the plate 1. j

An upstanding continuationof the longitudinal wall 6 is bent arcuately inwardly at.

, edge portion of the horizontal part of a clamp plate 8 is adapted toprotrude beyond the adjacent longitudinal edge ofthe rail base, so that the same will engage under the inwardly bent flange 3 of the base plate 1, as is clearly shown in Fig. 2.

The opposed clamp plate 9'is longitudi nally thickened at 12, and formed with a. plurality of threaded horizontally disposed sockets. These sockets are formed in the plate 9 at intervals throughout the longitudinal length thereof.

An abutting bar 13 has its outer surface curved to facilitate its engagement in association with the arc-uate wall extension 7.

The inner surface of this bar is substantially vertical and provided with a plurality of.

threaded horizontally extending sockets, each 'of which is located directly opposed from. a

complementary opening in the clamp plate 9.

The threaded sockets in the abutting bar 19, are adapted to receive one end of the respective screws of the threaded members 14. The opposed threaded sockets in the plate 9 are adapted to receive one end of the reversely threaded members 15. The opposed threaded ends of the threaded members 14 and 15 respectively, are adapted for threaded engage ment within the threaded bore of a sleeve 16, the sleeve 16 being formed with wrench engaging bases 17 i It will be clearly seen that when the rail has been properly positioned upon-the base plate toward one longitudinal edge thereof, that by inserting the plate 8 in the position clearly shown in Fig. 2, and the opposed plate 9, in a position against the opposed surface of the rail web, the construction is then in a position whereby the clamp plate may be tightly engaged against the rail web.

By rotating the sleeve 16, the threaded elements 14 and 15 respectively, will be fed outwardly effecting a force against the plate 9, as well as the abutting bar 13. By this action, the plate 9 is tightly engaged against one side of a rail web, while the abutting bar 13 shifts the plate 1, or the rail end if the plate I has already been secured to the lie, so that the opposed plate 8 will be tightly forced a ainst the rail web by the inwardly bent flange 3. Having thus described my invention, what I claim as new is 2- 1. In a rail joint securing structure, a base plate, upstanding flanges at the opposed longitudinal edges of said plate, a clamp plate adapted to be disposed between the rail and one flange of the base plate, a clamp plate at the opposite side of the rail, a movable elongated bar adapted to engage the inner side of the opposed longitudinal flange, and expansion means interposed between the second mentioned clamp plate and the elongated bar, whereby the clamp plate will be causedto tightly engage the opposed side of the rail ends, when the same is actuated.

2. In a railjoint securing structure, a base plate, upstanding flanges at the opposed lon gitudinal edges of said plate, a clamp plate adapted to be disposed between the rail and 7 one flange of the base plate, a clamp plate at the opposite side of the rail, a 'movable'elongated bar adapted to engage the inner side of the opposed longitudinal flange, and reversely threaded expansion means interposed between the second mentioned clamp plate and the elongated bar, whereby the clamp plate will be caused to tightly engage the opposed side of the rail ends, when the same is actuated.

In testimony whereof I aflixmysignature,
